There isn't much certainty under center for Oklahoma entering 2015, and one quarterback is looking to take advantage of the wide-open race.

After starting three games in 2014, Colleyville Heritage graduate Cody Thomas is doing whatever he can to get that starting job, perhaps even giving up a future professional baseball career in the process.

Thomas tweeted Tuesday that he would not be playing baseball for Oklahoma in 2015 to instead focus his efforts to the gridiron.

Thomas started three games for OU in 2014 after an injury to starting quarterback Trevor Knight. After Knight struggled for much of the season, it was seen as a chance for Thomas to prove he could be the full-time starter, but he didn't impress many.

He finished the season with 342 yards on 30-of-66 passing with two touchdowns and four interceptions over seven games played.

Coming out of Colleyville Heritage in 2013, Thomas was the No. 8 player in the SportsDayHS Top 100 and the top quarterback recruit in the area. Rivals rated Thomas as a four-star recruit and the No. 7 quarterback in the country.

He wasn't just sought for his football prowess, however.

Thomas was selected in the 2013 MLB Draft by the New York Yankees in the 30th round, No. 914 overall, as an outfielder.

Instead of heading to the minors, Thomas came to Norman, where he played both sports a year ago. In his first season on the diamond, he saw action in just 14 of the team's 58 games, earning one start. He was 1-for-14 with an RBI single, two strikeouts and a walk in his limited time.

He leaves baseball behind for now, and a totally-focused Thomas could add some extra intrigue to the OU quarterback battle. Along with Thomas, Baker Mayfield will be eligible to play and compete for the job with 2014 starter Trevor Knight, as well as redshirt freshman Justice Hansen.
